# Hardware Sizing

The hardware compute and storage requirements for MOSIP core platform are estimated as below.

### Production

#### Compute

Compute hardware estimates for a production deployment:

| Module                 | Capacity                        | Servers | Configuration         |
| ---------------------- | ------------------------------- | ------- | --------------------- |
| Pre-registration       | 7200 pre-regs/hour\*            | 10      | 4 VCPU\*\*, 16 GB RAM |
| Registration Processor | 200,000 registrations per day   | 80      | 4 VCPU, 16 GB RAM     |
| ID Authentication      | 2,000,000 auth requests per day | 20      | 4 VCPU, 16 GB RAM     |
| Resident Services      | 7200 resident services/hour\*   | 10      | 4 VCPU, 16 GB RAM     |

\* Average throughput

\*\* VCPU: Virtual CPU

We estimate 30% (approx) additional compute capacitiy for administration, monitoring and maintenance. This may be optimized by the System Integrator.

**Notes**

1. High availability is taken into consideration with assumed replication factor of 2 per service pod/docker
2. The above estimates **do not** include compute servers needed for
   1. Database
   2. HDFS/CEPH
   3. [Bio SDK](https://docs.mosip.io/1.1.5/biometrics/biometric-sdk)
   4. [HSM](https://docs.mosip.io/1.1.5/build-and-deploy/hardware-security-module-hsm-specifications)
   5. [ABIS](https://docs.mosip.io/1.1.5/biometrics/automated-biometric-identification-system-abis)
   6. Virus scan
   7. Load balancers
   8. External IAM
   9. Disaster recovery

#### Storage

Storage estimates for production deployment:

**Database and HDFS/CEPH**

[MOSIP Storage Requirement Calculator XLS](https://github.com/mosip/documentation/blob/1.1.5/docs/_sources/hardware_sizing/MOSIP_Storage_Estimate-v1.1.xlsx)

**Appication and system logs**

* Application logs

| Module   | Unit              | Raw log size |
| -------- | ----------------- | ------------ |
| Pre-Reg  | 100 pre-regs      | 20 MB        |
| Reg Proc | 100 registrations | 200 MB       |

The above estimates are approximate, and may inflate if, for example, there are too many exception traces.

The logs may be compressed and archived after a week or so. The compression ratio achieved with tar+gz utility is 15-20.

* System logs

To be estimated by System Integrator according to the deployment

### Dev, QA, Staging, Preprod

Additional compute and storage is needed for the following setups.

| Environment    | Setup   | n Servers | Configuration     | Storage    |
| -------------- | ------- | --------- | ----------------- | ---------- |
| Dev            | Sandbox | 13        | 4 VCPU, 16 GB RAM | 128 GB SSD |
| QA             | Sandbox | 13        | 4 VCPU, 16 GB RAM | 128 GB SSD |
| Staging        | Sandbox | 13        | 4 VCPU, 16 GB RAM | 128 GB SSD |
| Pre-production | Cell    | \*        | 4 VCPU, 16 GB RAM | \*         |

\* To be decided by the country/System Integrator.
